Global automotive brand, Stellantis and PPG have teamed up with a new sealer tech to add to efficiencies in the paint workshop.
Stellantis that includes numerous motoring brands such as ing Jeep, Maserati, Chrysler, Peugeot and Ram, has incorporated ithe new PPG CORASEAL® 4-Wet Sealer in Stellantis’ light commercial vehicles (LCV) production.
PPG’s Coraseal 4-Wet Sealer promises to cure in just one step, versus up to three steps required for traditional technologies, delivers sustainability benefits for automotive OEM paint shops by reducing energy usage and CO₂ emissions.
Automotive OEM paint shops normally use a curing process comprising a sealer oven, primer oven, and topcoat oven.
The PPG B1:B2™ process (also known as the 3-Wet system) reduced this to just the sealer oven and topcoat oven.
The latest PPG Coraseal 4-Wet Sealer takes it one step further where only the topcoat oven is required. The system is compatible with most waterborne and solvent-borne systems.
Global presentation
The results of the implementation at Stellantis’ LCV plants were presented in Berlin in July at the Strategies in Car Body Painting conference.
“Transitioning to the PPG Coraseal 4-Wet Sealer offers several sustainability and performance benefits to OEMs,” PPG Sustainability Business Partner, Automotive OEM Coatings Thierry Destruhaut says.
“When compared to the 3-Wet system, it can lead to a reduced environmental impact, reducing energy consumption by nearly 8 per cent, cutting CO₂ emissions by nearly five per cent and enhancing productivity.
“Additionally, the need for fewer curing steps also simplifies maintenance processes and reduces costs.”
